It annoys me in part because we actually have Banish IV, it's just only on summoner's Light Spirit (and at a relatively modest level I might add).

I do sort of wish WHM had better damage spells. They'd still be limited as they only have one element, but at least then it would be easier to participate in battles while leveling up in this age of using trusts for XP. They'd be able to add a bit of damage when nobody needs a heal as well. Not to the extent that it would be expected for efficiency, but more just to fill the time and burst skillchains.

It is rare in MMOs today that a class is so singularly oriented to healing that they can't really do anything when healing isn't needed.
